securely.andreducing.` the necessity of inserting so-calledquoins maartype frame and in some cases eliminating such use.

Other features and the construction of our device are hereinafter fully set forth reference being had to the accompanying drawing in which:

Fig. 1 is a plan view of an ordinary type-form chase and a type-form locked in diagonal position thereon by our improved lock-up set.

Fig. 2 is a lower edge view of Fig. 1.

Fig. 3 is an enlarged detail plan view as at the lower right corner of the type form in Fig. 1 and including a modification embodying an adjustable expansion device.

Fig. 4 is an edge view of` the inner part of our lock device as on line 4--4 in Fig. 3.

Referring to the drawing by reference numerals 5 designates a flat, quadrangular frame of a type Well known in the printing eld and in the opening of which type-forms of various sizes are removably fixed between the four elongated faces, interior faces 6F of the innermost four of a series of spacing bars or furniture of various widths as needed, such bars or furniture being also well known in the printing field. Some of the bars or furniture may be spaced apart and parallel as to thebottom and left side (Fig. 1) and socalled quoins 7 inserted in said spaces to force the inner bars 6 inwardly and clamp the typeform 8 in place. However in many instances the type-forms are required to be set in angular, or oblique positions and this requires, in means hitherto used, triangular filler blocks or special molded fillers all of which to o-ur knowledge have proven inefficient. Our invention embodies a set of blocks 9 usually four in number, each block Awith two outside faces at right angles to fit into the rectangular corner at the intersection of the innermost bars 6. These blocks pro-vide the basic anchoring or setting means cooperating with other members to adjustably retain the typeform in any desired angular position. It is obvious that the type faces are elevated or in a plane higher than theluppenfaceof iframe-5 (see Fig; 2 )1. i Each block 9 `is-A formed witlraninner-iarcuate,IV i serrated face-191,L the-icenterofcurvaturethereof` f beingona` line -inWard-ly'and-f`diagonallygfromthe?

In Fig. 1, A designates the quadrangular inner opening of the frame within which the typeforrn 8 is laid in the desired angular position, spacer bars or furniture 6 of such size being used that enough room is left at the four inner corners to insert a block 9 at each such corner. Each inner or auxiliary block 10 is then matched with its block 9 and their serrated faces in mesh, the position of each block 10 being governed by the adjacent angular position of the form 8. In Fig. 3 the inner edges of each auxiliary block 10 is shown parallel to an adjacent side of the typeform and spaced therefrom by furniture 11 as needed, then the quoins7 are adjusted to press the form inwardly and secure it in place rigidly.

We do not depend entirely however on the squeezing action of the quoins '7 and in the lower right hand serrated device in Fig. 1, and in enlarged detail in Figs. 3 and 4, we have'illustrated an expansion type of block l0 which has certain important features and which `construction may eliminate the use of the quoins 7.

In Fig. 3 the mark identified by numeral 12 designates the common center for the serrated faces 9F and 10F and 13 on block` 9 designates radial markings by means of which one setting ofthe two members 9 and 10 facilitates the setting of the other 3 lock-ups, 14 designating a single radial mark on member l0.

The expansion type of lock-up member is similar to the type above described, in general appearance, but adjacent the inner straight edge of block 10 we provide another elongated block 15 preferably of the same length as 10 and connected thereto in parallel relation by a rigid threaded stud 16. Each such stud projects into a central bore 10S of member 10. 16N is a nut on the stud adapted to be actuated on the threads i to spread the members 10 and 15 to lock the typeform. 17 are a pair of dowels fixed in member 15 and slidably engaging registering apertures in the opposite member. Obviously, any suitable wrench may be used to turn the nut 16N.

The structure and use of our lock-up set has herein been'quite completely disclosed. To the printers craft the operation of and advantages of our locking devices will be readily and clearly understood.

The preferred construction of our invention has been `fully disclosed and illustrated but modications details of structure, proportions of f parts etc., may be made without departing from the scope and spirit of the invention. One modification is illustrated for example as in the lower right hand lock-up device in Fig. 1 in which the nut 16Nof the stud 16 is located in a central recess 10R of member 10 instead Yof rin4 a recess 15C of member 15 as in Fig. 3.

We claim:

1. In combination, a non-skid type form holder forretaining type-forms in a predetermined angular position within a rectangular frame;l said holder-:means comprising a set of angularly adjustable members, each comprising an outer and an inner block, the outer block having two faces at right angles to fit a cornerrwithin a frame and formed further with an inner curved and sery rated face, and an inner block with a corresponding serrated face, said inner block having an inner straight face adapted to engage a side of a type form near oneof its corners, and an expanding device comprising the formation of said inner block intwo'expansible members slidably retained in parallel relation, one member having the serrated face described and the other member comprising an elongated bar inwardly of the inner edge of said serrated member, a threaded stud Xed in the bar and projecting into a regstering bore in the serrated member, and a nut on the threaded stud to engage the serrated member When turned, to spread the parts as may be required, for the purpose set forth.

2. In combination, a non-skid type form holder for retaining type-forms in a predetermined angular position lwithin a rectangular frame; said holder means comprising a set of pairs of angularly adjustable members, each pair comprising an outer block with two outward faces at right angles to fit a corner Within a type frame, an inner block adapted to be contacted with the inward face of the first described block diagonally opposite the outer faces thereof, in selective angular positions, said inner block having an inner straight face adapted to engage a side of the type form near one of its corners, and an expanding device comprising the formation of said inner block in two expansible members slidably retained in parallel relation, one member having the contact means stated and another member comprising an elongated bar parallel to the inner edge of said contact member, a threaded stud fixed in the bar and projecting into a registering bore in the inner block member, and a nut on the threaded stud to engage the inner block inember when turned, to spread the parts as may be required, for the purpose set forth.
